Black spots on surface rendered model when switching from one window to another
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
I’m using the latest ‘unstable’ release of VTK (5.1.0) in order to develop a tool able to generate 3d models from dicom images and to view them in stereo mode.
The problem: when I have two windows opened (one is the 2d viewer, the other is the 3d viewer) in the 3d viewer I correctly visualize a surface rendered model in stereo mode (CrystalEyes, active stereo mode converted to the passive one by using a nVidia Quadro FX3500 graphics card), but if I switch on the other window (keeping the 3d viewer window opened in background) and then I return on the 3d viewer window the model becomes partially black!
If on the 3d viewer I switch to the anaglyph stereo mode, and then again to the CrystalEyes ones, the 3d model is probably recomputed and the black spots disappear.
This problem doesn’t happen if I use the last stable version of VTK (5.0.3), but I need to use the new one.
